Title: Speed control method for servo motor
Inventor: NIN CHIYUUHIYUKU
IPC: H02P29/00
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To converge speed control error constantly to 0 as much as possible regardless of disturbance by inputting a control torque value added with a disturbance torque value to a mechanism system model while inputting the control torque value to an imaginary model and calculating an estimated speed value. SOLUTION: A feedforward control section 4 calculates a feedforward control input T2 by differentiating a target speed input ωd*. An adder 12 inputs the difference between the target speed input ωd* and a negative feedback speed output ω to a proportional control section 5 where a proportional control input T1 is calculated and combined, by means of an adder 14, with the feedforward control input T2 to form a control torque input Tu. Subsequently, the control torque input Tu is directed to the input side of a mechanism system model 1 and an imaginary model 2. The control torque input Tu is added with a disturbance TL by an adder 16 and a correction torque τ1 is subtracted therefrom to form a final input torque τ*. Other branched control torque input Tu is inputted to the imaginary model 2 where an estimated speed is calculated.

Title: Continuous input/output interruption monitor processing system
Inventor: NAKAJIMA YUKIO
IPC: G06F13/12
Filed: 1986-09-05
Abstract: PURPOSE:To exactly detect a hardware fault of a peripheral equipment by providing a means for inhibiting a restart processing of an input/output request being in a waiting state, and also, inhibiting a start of an input/output processing, when a rejection of an input/output start instruction and an interruption for informing the usable state have been repeated with a high frequency. CONSTITUTION:When an interruption has been generated with a high frequency, it is inhibited stepwise to issue an input/output start instruction by a restart processing inhibiting part 25 and an input/output processing start inhibiting part 26, in such a way as an inhibition of a restart processing, and subsequently, an inhibition of a start of an input/output processing, without deciding it to be a hardware fault immediately. Even in case of a state that a new input/ output start instruction is not issued by said inhibition, when the interruption has been generated with a high frequency, it can be recognized clearly to be a hardware fault. Especially, the inhibited state is set stepwise such as the inhibition of the restart processing and the start inhibition of the input/output processing, therefore, an influence by setting the inhibited state in case of a normal state can be suppressed comparatively small.

Title: Arithmetic unit for rational number
Inventor: NAKANO HIROSHI
IPC: G06F7/38
Filed: 1986-09-05
Abstract: PURPOSE:To accelerate the arithmetic calculation of a rational number by a hardware, by abbreviating the number through the use of a fast multiplier/ divider. CONSTITUTION:By setting equations 1 and 2 through the use of a Gauss' symbol 'r' [maximum integer not exceeding (r)] for an arbitrary real number (r), the normal continued fraction expression 3 of the (r) can be obtained. If the (r) is the rational number, development is completed in limited number of times (rm=bm), and if the (r) is an irrational number, the development is not completed in the limited number of times. By expressing the n-th convergent of the normal continued fraction in equation 4 in a form of irreducible fraction, and setting them as P-1=0, P-1=1, Q-2=1, and Q-1=0, recurrence formulas 5 and 6 can be obtained. At this time, by setting a (bn) as rnRn-2/Rn-1, and the (r) as r=r0, the Rn-2=P, and the Rn-1=Q, equation 7 can be obtained. The (bn) can be obtained as the quotient of division at time of setting a dividend as Rn-2, and a divider as Rn-1.
